About Blow Molding

Blow molding is a versatile, cost-effective manufacturing process that uses air pressure to inflate soft plastic into a mold cavity. The result is objects that are stronger and lighter than those produced by other plastic fabrication methods. Technological and engineering advances continue to expand the number of applications that can be successfully addressed with the blow molding process. Leading-edge industrial innovators continue to explore the benefits of blow-molded plastic products. These include:

  • Lower mold costs
  • Competitive unit costs
  • Faster cycle times/increased output
  • Flexibility of part design
  • Lightweight durability
  • Strong part performance
  • Superior corrosion resistance
